To all whom it may concern." a

Be it known that I, JULIUS KosAN, a citizen of Hungary, residing at Cleveland. in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Stackers for Threshing Machines. of which the following is a specification. I

This invention relates to thrashing machines such as are used for thrashing wheat, orother grains havingparticular reference to an arrangement of parts to facilitate.

transportation of the 'mach'ine place to another. I

The invention has for an object to provide a thrashing machine [capable of traveling from place to place under its own power, the motor or engine being adapted to drive the running wheels or the thrashing machinery, as be-de'sired.

A further object relates to the mounting of the stacker on the machine whereby said stacker may be extended to operative position when the machine is operating, or folded upon the top of' the' machine when the latter is traveling from one place to from I one another. I

' For further comprehension ofthe invention, and of the objects and advantages thereof, reference" will be had to the followand to the appended claims which the variousnovel features of the lIlVQIlillOIl are improved thra'shingymachine.

more particularly set forth.

Ashereshown my improved thresher coniprises a truck frame made in the usual manner of's'teel'beams and mounted on front wheels 11 and rear wheels 12, the front Wheels being dirigibleby the usual steering wheel 13. Uponthe front end of the frame is a gasoline motor, indicated generally at 14. This motor drives a longitudinal shaft 16 which is connected byfatrain of spur gears 17 with another longitudinal shaft 18 located at onesi'de of the frame 10. .Rotatively mounted on the rear end of shaft 18 is a bevel gear 19 meshing with a like gear 20 on atransverse shaft21 connected, by achain 22 looped over suitable sprocket wheels, with the rear axle 23. Fixed to gear 19i's a' clutch element 24 adaptedto be engaged by a second clutch element 25 feathered on the shaft 18 and adapted to be moved into and out of engagement with the clutch member 2-1 by a lever 26' provided with the usual means for looking it in adjusted posi shaft 33 mounted on a verticalframe 34 projected upwardly from the frame, 19 in frontof the body 35 of the machine. This shaft 38 has also fixed thereon other pulleys such as 86 from which a suitable system of belting, indicated generallyat 37, drive's the cylinder 38, fan 39, and other operating elements which are of usual construction. I The threshed' grain, comprising chait' and hulls, falls downward through a series of vertical tubes 42, passing through chambers 43 intowhich a series of nozzles 44, on a-p'ipe 45 leading from a blower 46, enter; This" blower is of the rotary type and its fan is mounted on, and driven by, the shaft 18. The chaff is separated from the grain by the blast from the blower 4:6,the grain fallingintobags or receptacles such as 47 under the chambers 43. p

' At 50 I have indicated a stacker which is of theusual detail construction and operation, and which may be operated by a belt which is'removed when the stacker is to rest onthe thresher body. As a feature of the invention this stacker, when not in'us'e and when the machine is'traveling from one place to another, is adapted to be swungove'r thetop'of the machine and rest thereon, as

indicated in Figure 3; The stacker, when'in use is supported" by a pair of posts 51 lo cated one at each side of the rear of the machine, being suspended therefrom by a pair of arms 52 pivoted to the posts, the

and inpropc'r operative relationto'the mech anism therein. The arms 52 are held on the posts by removable hinged bars 52. The

arms 52 are connected to the stacker at their lower ends by means of a transverse rod 53 (see Fig. 4?) which extends freely through the stacker and is fixed at its ends to the arms. On this rod are a pair of rigid fingers 54 which project over studs or lugs such as 55 on the sides of the stacker for a purpose which will later be set forth.

To swing the stacker to the position shown in Fig. 3 a pair of ropes 58 are connected at one end to the rear end of the stacker, and lead forwardly to pass down between pairs of flanged pulleys 59 mounted in the upper end of each of the posts 51 with their flanges in close adjacence, the ropes finally passing 1 downward onto drums 60 supported by brackets 61 projecting upwardly from the truck frame l0.- These drums are fixed on a shaft 62 on one end of which is a removable crank handle 63 suitable ratchet locking means 64: being provided. When the drums 60 are rotated, and the ropes 58 wound there on, the rear end of the stacker is swung upwardly and forwardly,as will be apparent. As this movement takes place the stacker and arms 52 fold upon. one another, jackknife fashion, allowing the front end of the stacker to sink, until the fingers 54 engage the lugs 55, the arms 52 and then swinging as a unit around the projecting top' rear portion of the thresher body 35. Connected to the stacker about midway of its length, is a second pair of ropes such as 66 which lead forwardly over suitable pulleys 67 on the deck 10 then rearwardly to a second pair of drums 68, smaller than the drums 60 and normally loose on the shaft 62 and which may be rotatively connected therewith by clutches 69 operated by levers 70. When the stacker reaches an approximately vertical position, the drums 68 are momentarily clutched in, the ropes 66 then acting on the stacker to move it forward past dead centre position. As the stacker swings forward the ropes 58 are transferred to the forward ones of the pulleys 59, and the drums 60 are then rotated to allow the stacker to swing downward and forward until it rests on top of the thresher, a suitable support 71 being provided on top of the frame element 34 to receive the forward end of-the stacker. As will be apparent, the shaft 62 and crank handle 63 provide driving'means for the drums 60, while the clutches 69 constitute releasable means for operatively connecting this drive means with the drums 68.

The posts 51 are also adapted to be lowered to a position resting on the truck frame 10 and to thisend each post is mounted on a spur gear 75 which rests on a rack -76 ex tending along the frame 10. Connected to the lower end of each post is an endless band 77 which'engages-over front and rear drums 78 and79 the latter being fixed on a trans verse shaft 80 on which is a crank handle 81 and to which ratchet locking means 82 is applied. Pivotally connected at one end to the body 35, at the sides thereof, are a pair of rigid links such as 83 which are pivotally atband 77 which pulls it tightly against an abutment 85 on the end of the frame 10. When the posts are to be lowered the ratchet locking means 82 is released, the U-brackets 84 removed, and the drums 79 rotated to move the lower ends of the posts forwardly along the racks 76, the posts swinging on the links 83 until they assume the position shown in Fig. 3. It will be understood of course that the ropes 58 will be sufficiently loosened to allow the posts to assume this position. When the posts are to be raised, the above operation is reversed.

To cool the motor 1a, when it is running to operate the thresher, a fan is mounted in front of the motor and directs a blast of air through the radiator thereof, this fan being shown as driven by a belt 91 from a countershaft 92 connected by bevel gears 93 and 94 with the engine shaft 16.

When the machine is to travel from one place to another, the stacker 50 and posts 51 are moved to the position shown in Fig. 3, the belt 30 is thrown off and the clutch 25, 24 engaged to operatively connect the motor to the rear wheels.

Having thus described my invention what I claim as new and desire to protect by Letlows j 1.
